1.1 Product definition
This document contains the dimensional, optical, mechanical and environmental performance requirements of a fully installed optical fibre wall or pole mounted box for up to 288 fibre splices, in order for it to be categorized as a European standard product.
The typical configuration is splicing of incoming fibres to optional splitters, connecting on the other side to outgoing fibres.
A box is a protective housing containing a fibre management system with splice trays of various fibre separation levels. The box can contain one or more of the following:
storage and routing for fibre and cable;
uncut fibre cable storage;
splice trays;
passive optical devices (optical splitters or WDM).
A box can be installed on a vertical indoor or outdoor surface above ground level. If the box is required to be relocatable with cables attached, the following additional tests are expected to be performed:
cable bending;
cable torsion.
This document specifies the number of splice trays and splice capacity for each fibre separation level. The maximum capacity is 288 splices. For housings with a higher number of splices, EN 50411-4-1 (street cabinets) can be used.
Boxes for fibre splice and patchcord connections are covered in EN 50411-3-4.
